CONCRETE CAP ANI) SILL BLOCK FOR BILDING PURPOSES.

Application filed March 6, 1924.' Serial No. 697,261.

To'aZZ whom t may concern:

useful Improvements in Concrete Cap and Sill Blocks for BuildingPurposes, of which the following is a specification sufficient to enable those skilled in the art to which the invention appertains to utilize the same;

My improvements relate to concrete building blocks designed to be used as capping and sill supporting blocks for walls constructed of hollow apertured bricks or sections in a manner well known in the building art, such for instance as cement, terracotta, brick or concrete foundation and cellar walls,-my object being to eliminate the deleterious effects of moisture in so kfar as such walls are concerned, by promoting air circulation through the wall while seal-V ing the top thereof, at the same time insuring the proper alignment and support of the sill plates, and protecting them against ground moisture, all as hereinafter fully set forth, the invention consisting in the specific construction of cap block herein described and claimed, whereby these and other advantageous results are attained; and distinctive features being the formation of each sill and cap block with a lateral aperture in the interior face thereof communieating with the internal air channel therein, and with a longitudinal top channel for the reception of plastic or green cement to be used in leveling and surfacing the sill plates in such manner that when such leveling cement is set the sill will be permanently leveled and fixed in position as well as sealed against seepage of moisture from below; an incidental feature in this connection being the provision of the cap block with a stay bolt for use as a sill anchor to insure stability.

In the accompanying drawings I illustrate a practical embodiment of the essential features of my invention as applied to wall construction of the character designated, although I do not limit myself to the identical configuration and arrangement of parts shown by way of exemplication, since modifications in minor details and equivalent mechanical expedients may be resorted to with like results and without departing from the spirit and intent of my invention in this respect.

Vith this understanding Fig. l represents a top view of a portion of awall constructed in accordance with my invention, the view including a corner of the wall;

Fig. 2 is an elevation of the wall shown in Fig. l partly in section;

Fig. 3 is a perspective view of the upper side of my'improved cap block as Vformed for the main portion of a` wall;

Fig; 4; is a perspective view of the under side of the cap block shown in the preceding figure;

Fig. 5 is a perspective view of the upper side of a cap block modified in construction for use as a corner block;

Fig. 6 is a sectional detail, upon a larger scale, of a cap block and sill platemounted therein.

My new cap and sill block C, is formed on its underside with the longitudinal air space or passage c, extending from end to end thereof, as shown more particularly in Fig. 4, of the drawings, and with a lateral opening c, on the side of the block C, which is designed to form a component part of the inner face of the iwall, said lateral aperture c', functioning as the inlet and exit for air to and from the hollow spaces, not only in the cap and sillblock C, themselves, but also to the air spaces in the courses of lower blocks or sections B, B, constituting the body or basic structure of the wall. These' apertures c', by establishing communication between the cavities in the wall blocks and the interior of the cellar or other compartment thus enclosed, insures a natural circulation and replacement of air within the wall which tends constantly to eliminate moisture and establish uniformity of temperature and dryness throughout.

The top of my cap block C, is formed with a trough c2, for the reception of plastic cement p, on which the sills S, are laid and trued or levelled in accordance with conditions and requirements the subsequent setting or hardening of the cement insuring stability in this respect,-this embedding of the underside of the sill S, in the cement p, also eliminating the possibility of air space between the inside and outside of the structure. Furthermore, this embedding of the sills in the cement p, within the trough c2, in the top of the cap blocks C, effectually protects the sills against moisture from below.

In order to stabilize. the top structure of the Wall, considering my cap block C, and

`sill S, as unitary in this respect, I provide certain of said cap blocks C, with tie bolts t, the bases of Which are embedded in the blocks during the formation thereof, these tie bolts being of suiiicient length to exl. A cap block of the character desig-V nated, formed on its underside with a longitudinal air space, and wlthalater-al opening on the inner `side ofthe block corn-y niunicatin'g with said longitudinal air space, said cap block being also formed on its upper side with a longitudinal trough for the reception of plastic cement, substantially`in the manner and for the purpose set forth.

2. A cap block of the character designated, formed on its underside with a longitudinal air space, and with a lateral opening on the inner side of the block communicating With said longitudinal air space, said cap block being also formed on its upper side Withv a longitudinal trough for the reception ofl plast-ie cement, together with a sillvv stay bolt thefbase of which is embeddedv in said cap block, substantially in the mannerfset forth. l
